LEO Satellite Networks Assisted Geo-Distributed Data Processing
IEEE Wireless Communications LettersNowadays, the increasing deployment of edge clouds globally provides users with low-latency services. However, connecting an edge cloud to a core cloud via optic cables in terrestrial networks poses significant barriers due to the prohibitively expensive building cost of optic cables. Fortunately, emerging Low Earth Orbit (LEO) satellite networks (e.g.,

Optimal Handover Strategies in LEO Satellite Networks
Existing theoretical analyses of satellite mega-constellations often rely on restrictive assumptions, such as short serving times, or lack tractability when evaluating realistic handover strategies. Motivated by these limitations, this paper develops a general analytical framework for accurately characterising the ergodic capacity of low Earth orbit ...
